Sophistication = Experience + Math

by Mitchell Vexler

“What we have been seeing worldwide, from India to the UK to the US, is the rebellion against the inner circle of no-skin-in-the-game policymaking “clerks” and journalists-insiders, that class of paternalistic semi-intellectual experts with some Ivy league, Oxford-Cambridge, or similar label-driven education who are telling the rest of us 1) what to do, 2) what to eat, 3) how to speak, 4) how to think… and 5) who to vote for.” (Nassim Taleb)


Expanding upon this thought is the use of technology to cover for, or entice, the lack of critical thinking about what and how to invest. 

The internet is full of charlatans and fraudsters who promote returns that are not feasible, business models that are economically upside down, designed to create revenue for the middle man who delivers no value, and in many cases delivers economic disaster for the investor. Just as bad, the charlatans want people to believe they, the charlatans, know all about real estate (or stocks) and you (person or corporate) should rely on them instead of learning and doing for yourself. This falls under the advice of “Teach a man how to fish, and he will eat for a lifetime”.  [As a side note, the average real estate yield to the largest Pension Funds was 6% in 2020. How is this possible with legions of allegedly smart people and middle men?]


Yes, this problem is not just at the individual investor level, but also at the corporate leadership level and many have fallen into the same trap. The problem has become the one-eyed following the blind, in that the larger the corporate structure, the more CYA problems arise. Many real estate CEOs are pitchmen who have never designed, built, managed or sold an asset on their own weight, and then turn around in their own company and layer analysts and appraisers to create the illusion of backstopping the investment (CYA).  Their real skill is not the real estate but the creation of illusion of either their own or the company’s expertise.  It comes down to AUM, Assets Under Management. The more AUM, the more revenue the company makes which means the company is the middle man and the middle man is not dependent on the underlying profitability of the Asset. In plain English, the underlying assets is of secondary concern (if at all)


The above is not to say that certain real estate business models are not worth pursuing such as investing in existing B, C, or D quality assets with the idea of fixing them and increasing the rent. The overriding problem with this model is that the assets are old, there are thousands of investors chasing the theory, and the theory has multiple flaws. What if after retrofit, it turns out the local market can’t support an increase in rent???  The point being that finding the true economically viable turn-around investment takes a sophisticated eye and the ability to manage to completion. 


On one of our projects, we received a call from a local bank that wants to provide a 70% construction loan to 30% equity. Prior to this some of the lenders were 60-40. The Local Construction Lender provides a 24-month construction term, 24 month mini-perm, and at 4.5% Interest. We created a “what if” spreadsheet, examining and comparing proposals that were received from Mezz Lender, Preferred Equity Lenders, 221d4, PACE, and a combination. Although the IRRs were strong with the Mezz, Pref, and 221d4 the truth is that under all 4 scenarios the cash flow till sale at the property level was minimal which is diametrically opposed to maintaining a healthy property so that when it is ready to be sold, the profits (capital gains) can be maximized.  It is also interesting to note that there are lots of issues under the hood with such programs like the 221d4 such as, no step-up basis upon construction completion, BSPRA which is cash not received as part of the loan making the project more expensive ($12-$15K per door) more than conventional financing.  Further the 221d4 requires 24% equity as compared to the 30% conventional. The point to the above, is that we have clarity and conventional financing with capital gains goal upon sale is the right strategy to maintain a healthy cash flow during operations and build the property $12K to $15K less per door without all the financial engineering and associated fees.   Studying who is getting what money and why, brings us full circle to AUM. The question becomes, what is the real cost of the financial engineering, or Kabuki theater as I like to call it. 


Over the years, it has become more apparent, that these academic CEOs (aka charlatans) who feel entitled to run our lives and resident’s lives, are not strong in math or policymaking, and just copy what they saw somebody else doing. They hide from investors and they hide from the public (try and get a response by email from them). They don’t want to study facts. They want to create illusions and the problem with illusions is that they are not based on probabilities.     


In investment, probabilities are all that matters.  Everything else is just noise.  In the options market, probability is measured by Delta, Gamma, Vega, Theta, Rho, as the first derivatives (aka the Greeks), followed by Vomma, Vanna, Speed, Charm, Lamda, which leads to the determination of skew, probability density function and then the current value of options based on implied volatility and the underlying stock price based on the Volatility of Price.   It is about creating and managing to a reasonable and probable yield within a reasonable standard deviation of volatility.


At Mockingbird we use this model heavily and then deploy the next level of Monte Carlo Analysis both in terms of value of the underlying and even looking for issues before they arise.


Probability and the math necessary to derive the probability is about critical thinking (aka Sophistication). 


The Black Scholes Formula which uses all the above Greeks, has limitations which are:

  1. the underestimation of extreme moves, yielding tail risk, which can be hedged with out-of-the-money options;
  2. the assumption of instant, cost-less trading, yielding liquidity risk, which is difficult to hedge;
  3. the assumption of a stationary process, yielding volatility risk, which can be hedged with volatility hedging;
  4. the assumption of continuous time and continuous trading, yielding gap risk, which can be hedged with Gamma hedging.


In short, while in the Black–Scholes model one can perfectly hedge options by simply Delta hedging, in practice there are many other sources of risk.


Results using the Black–Scholes model differ from real world prices because of simplifying assumptions of the model. One significant limitation is that in reality security prices do not follow a strict stationary log-normal process, nor is the risk-free interest actually known (and is not constant over time). The variance has been observed to be non-constant leading to models such as GARCH to model volatility changes. Pricing discrepancies between empirical and the Black–Scholes model have long been observed in options that are far out-of-the-money, corresponding to extreme price changes; such events would be very rare if returns were lognormally distributed, but are observed much more often in practice. 


Yes, real estate and operating expenses can be hedged with options, but that is an entirely different discussion for another time.


With all the above said, the study of Volatility in Pricing (i.e. product type, demographics, business model) is why Mockingbird designs and builds its own properties, to create a high probability of profit, based on a real model, not emotion or illusion.

Often after writing an article I realize there is more detail and background information that would help to complete it. That is what is included here... a preamble of sorts.

A list of frauds and some links to evidence of fraud is presented. The Hidden Propaganda socialist Model is used by both political parties. The common enemy is inflation & those responsible. None of this would exist if the government and courts were doing their job. So...Why Gold? Why Silver? Why Now?

Report by Mackenzie Eason can only be viewed as a whitewash, because the report is inconsistent & wrong: could not have looked at the requirements or math of USPAP, did not examine the software override allowing manipulation of values; and would take 3 cross examination questions to completely prove the whitewashing.

Being highly levered is an assurance of mass destruction. At the breaking point, will spin out of control, as everybody heads for the exits simultaneously. And it's not just Private Equity structures, but School Districts, that are over-leveraged, requiring bailouts/additional taxes to pay for their financial crimes.

When economists say the economy is good… which economy, who’s economy, Wall St economy or Main St economy? There’s recession, if not depression, on Main St. Mom & Pop are over-burdened by property tax assessments, inflated to cover school district bond debt & compound cumulative interest, that can never be paid off.

This Open Letter is a bit of a premonition given my experience with politicians, economists, and fraudulent reports. I could be wrong, but let’s see how this plays out in the next few days.

Clock's ticking. Every moment, that passes without property tax repealed & replaced w/ uniform states sales tax, more households are in jeopardy of bankruptcy or losing home. Are you in that position now; are you struggling w/ monthly payments; how much more property tax before you're forced to sell... or go bankrupt?
February 20, 2026
In Texas, the system itself (CADs, IAAO, TAAO, AG, TEA, State Comptroller, others) all violated the laws & framework they are supposed to represent. Violations enabled fraud to start & grow and are now necessary to feed compound-cumulative interest on fraudulent school district bonds. Vexler's suit exposes this & them.
February 19, 2026
NY Federal Reserve reported US household debt reached $18.8 Trillion in Q4 2025, up 1% ($191 Billion) from previous qtr. We are at the end, where the compound interest on top of the compounded fraudulent debt cannot be paid down or off. The math is the math... socialism ends when you run out of other people's money.

As an offshoot of our main focus of property tax fraud & school district bond fraud, and in addition to Articles I wrote on socialist behavior (links provided), a pattern of Cultural Decay in both corporations & people has emerged which is the fallout of socialism. Consider the common traits of items presented here.
February 17, 2026
Roughly 42 mil US households are in harm’s way of bankruptcy or of losing the roof over their head due to property tax fraud & school district bond fraud.

1/30/2026 Supreme Court of TX requested response from opposing counsel representing Denton CAD. We expect opposing counsel will put forth same nonsense to prohibit adjudication of fraud being perpetrated against every real estate owner & every citizen in Denton County. Perhaps SCOTX now sees the Constitutional issue.

January 30, 2026
If you acknowledge this list as “truths” or if you agree and can answer yes to a majority of these qualifying statements and questions, you should be… investing in Metals and getting involved in repealing all real estate tax in favor of the Uniform States Sales Tax.

Following up on article “socialism is a Noun” I kept thinking about psychology of socialism & proof not just in fact that it was a con from inception, but proof of why it self-terminates when it runs out of other people’s money to steal. Let's review a Bisnow article about proposed bond funding in Ft. Worth Texas.
January 26, 2026
There are many factors to consider with silver, gold, platinum (commodities). The Federal Reserve with no accountability & no oversight has been printing money, not backed by assets, to support the banks & cover the bond debt, i.e. cover compound cumulative fraud upon compound cumulative fraud. So, who owns the bank?!

January 14, 2026
The 2 largest purveyors of fraud in the U.S. are the Federal Reserve & the School Districts which own the CADs and this is the Civil Rights issue of our generation. In my humble opinion, the true solution is to Chain the Doors of the Federal Reserve and repeal all property tax in favor of the Uniform States Sales Tax.

State(s) Property Tax Codes are criminally violated, not just 1 or 2 sections of code, on an epic level, including failure to comply with Uniform Standards of Professional Appraisal Practice which is required in the code of law.

Every Citizen should be greatly bothered by any political party, official, or judge refusing to adhere to Constitutional law, as in the end, all citizens regardless of party affiliation end up paying for the fraud created. Socialism, a means to perpetrate/perpetuate fraud, should be codified illegal. Protect yourself.

There's a direct correlation to property tax fraud, silver scam, & printing of money via U.S. Treasury & Federal Reserve. The nexus is the creation of false value being fraudulent property valuation from which to steal tax revenue, fraudulent paper chasing paper from which there is no physical to back up the paper...

Your equity is being stripped while you sleep. CADs, School Districts, State Comptroller, Attorney General, Governor, Legislators all collude in promoting propaganda with taxpayer funds to make you to believe “it is for the children” & that there's nothing you can do about it, all while they commit crimes against you.
